  • RelevanceThe gene for CDK2NA generates several transcripts/proteins which differ from each other in their first exons. Three of these transcripts are generated by alternative splicing (isoform 1 a.k.a p16INK4A, isoform 2 and isoform 3 a.k.a p12), two of which are known to function as inhibitors of CDK4 kinase. One other transcript that is generated from this gene contains an alternate reading frame (ARF), with the first exon located 20kb upstream of the remainder of the gene(isoform 4 a.k.a. p14ARF, p19ARF, ARF). In spite of the structural and some functional differences, all the proteins encoded by the CDKN2A gene are involved in cell cycle G1 control.

    Lane 2 : Lysate from ARF positive H1299 cells

    Predicted band size : 14 kDa
    Observed band size : 15 kDa (why is the actual band size different from the predicted?)

Thank you for your patience. Regarding ab5953, unfortunately, we do not have more information about this antibody. We will update the on-line datasheet of this product as soon as we get more data. We apologize for any inconvenience caused.

Ab470 was tested by Western analysis on HeLa (weak signal at 1:500) and BT549 cells (strong signal at 1:1,000+). IF was done on BT549 cells.

This antibody has not been tested in IP, therefore we cannot guarantee results.

It is not known. Since it has been used for IF at 1:100 it may but at a low dilution.
